Yeah, I too was impressed by how many musicians we have here . . . wonder what that says about music and AP? Hmm. Oh well. That's the extent of my deep thought tonight. I'm too tired to take it any further!
K: We've not had the biting, but just recently went thru pretty much the same thing with ds hitting me -- clearly for fun and CLEARLY to get a reaction -- and my reactions ran the full spectrum as I tried to find one that made an impression on him. (Apparently, "NO! I don't like that!" and "That makes me Mommy sad." are the FUNNIEST things ever uttered by a human.)
: I eventually got out of it by just distracting him.
Wait, that's not true. I actually refused to pick him up in the midst of the hitting frenzy, bc every time I did, he would clock me in the face and laugh hysterically. Once I refused and said, "No. I don't want to pick you up right now bc you're making me sad." He freaked a little. I wondered at the time if I was using abandonment as a threat, but the truth was, I *didn't* want to pick him up and he WAS making me sad!!! And I never left him. In any case, I let him cry at my feet for about 45 seconds, then I picked him up and *quickly* redirected his attention.
Since then, each time I sense the hitting about to commence (it's more like tapping, really, but it's the thought that counts, I think), I say, "Mommies are not for hitting. Mommies are for hugging and kissing." and then I 1) get the heck away from him -- as subtly as possible -- so he can't make contact and then 2) redirect.
Hmm. Maybe this is IS on the topic of Touch!
I don't know if this will help you. I have found that for my little guy, going head-to-head with him with a resounding "NO" is just about the least effective thing I can do. He just has NO fear of me. Which is scary, when I'm in the moment and ovewhelmed and fresh out of ideas, and longing to resort to those old, learned patterns. But it's also wonderful, for all the obvious reasons.
Other thoughts on the biting?
